Ratchet device

. D. P. WEIR I RATCHET DEVICE Filed Feb. 6. 1926 in the groove the end of the sleeve 10 and occupies a posi' tion loosely engaging the outer side of the gear 26. The stops 13 slide into the cut-in grooves 10 and prevent the washer 13 from revolving on the sleeve 10.

The gear 14, plate 18 and in their respective positions by means of the nut 13 being adjusted on the outer end oi the sleeve 10 adjacent to the washer 13.

When the propelling power is applied revolving the gear )6 forward (to the right in the present instance) the cogs 28 are brought into mesh with the cogs 25 of the pinions 23 and simultaneously the rear lugs 27 of the gear 26 engage the stops 19 of the plate 18 forcing the plate 18 to revolve with the gear 28 (Fig. 2). This prevents the re tation of the pinions 23 during this opera tion and thereby-forces the gear 1 1 to rotate with the gear 26.

The pinions 23 adjust themselves automatically by means of the adaptability ot the bushing ca 5 21 to slide back and forth tracks 21. I

When the shaft 8 and consequently the gear 14 continue to revolve forward While the gear 26 is stopped the plate 18 is carried forward engaging the stops 19 with the front lugs 27 of the gear 26 allowing the pinions 23 to occupy positions Within the recesses 29, and to idly revolve while in that position. When the gear 26 is revolved backward (to the left in the present instance) the front lugs 27 of the gear26 are gear 26 are held brought into clutched engagement with the coupling stops 19 01'' the plate 18, thus leaving the pinions 23 occupying positions within the recesses 29, therel'iy forcing the plate 18 to revolve with the gear 26 and the pinions 23 to idle and revolve around on the gear let, consequently allowing the gear 14 to remain idle during this operation.

hat I claim is:-

1. The combination with a shaft having a driven gear wheel mounted thereon of a mutilated drive wheel, an intermediate plate, pinions mounted in said plate and engaging the driven gear wheel, and coacting coupling means on said drive Wheel and plate.

2. The combination with a shaft having a sleeve adapted to rotate therewith and a driven gear fixed to the sleeve, of a inutilated drive gear mounted on the sleeve, an

intermediate piate, bevel pinions revolvahly mounted in said platefor coaction with said gears, and enacting coupling devices on said drive gear andsaid plate.

3. The combinationwitha shaft end haw ing a tiredhushing and a driven gear tilted to the bushing, ot a nnitilated drive gear mounted on the bushing, an intermediate plate having slots therein and hevel pinions jonrnaled in the plate and occupying said slots for coaction with said gears, and complementary clutch lugs and stops on and drive gear and plate.

' In testimony whereof I aliix my signature.
